Note However, if the SD Memory Card is write-protected, the verification results files will not be created.
The verification results files contain the results of comparing the Controller data and the data in a
backup file on the SD Memory Card in the CPU Unit for each data group. You can check the verification
results in the portion that gives the verification results for each EtherCAT slave. “Result=Matched” indi-
cates a data group for which no differences were found. “Result=Not matched” indicates a data group
for which differences were found.
The following table gives an example of the verification results for the following file contents.
• Matched: EtherCAT slave called Master and EtherCAT Slave Terminal E022
• Not matched: EtherCAT slave E001
* If EtherCAT Slave Terminals are set for verification, the EtherCAT Slave Terminal verification results file is cre-
ated. The detailed verification results for the EtherCAT Slave Terminals are given in the EtherCAT Slave Terminal
verification results file.
Note The verification results are given only for the EtherCAT slaves that were compared.

How to Check the Verification Results
File contents Description
[Verification Results]
; --- EtherCAT Parameters. ---
: --- See the VerifyResult_ECAT_NX.log
about detail result if NX mark is included in
square brackets.
[Master]
Result=Matched
[E001]
Result=Not matched
Factor=Verification error
[E002:NX]
Result=Matched
The slaves are indicated with the user-set device names. For an EtherCAT Slave
Terminal, “:NX” is added to the end of the device name.

The verification results are given as follows:
Result=Matched Same
Result=Not matched Different
